If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, what will come in place of ‘?’ in the following equation?
121 × 11 ÷ 28 - 3 + 46 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 49.
Given conditions: ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’
Given equation: 121 × 11 ÷ 28 - 3 + 46 =?
After interchanging the expression becomes:
= 121 ÷ 11 + 28 × 3 - 46
= 11 + 28 × 3 - 46
= 11 + 84 - 46
= 95 - 46 = 49
